Hitting a dead end

Hitting a dead end

Im looking for information on the parents of my grandmother and I think I found their names but cant go any futher than that. Im new to this but I feel Ive searched many records with no real answers. His name is John P. Hill born in Tennessee abt. Oct 1863 and her name is Permelia L. Asher born 1870. I think in Kentucky. Cant seem to find any death Records or anything other than the Census info.ThanksErnie
